Though the count in the Table after load is the same as the input file, they are all NULL.
I tried adding FIELDS TERMINATED BY X'A' for new line and also FIELDS TERMINATED BY X'D' for carriage return. Both times bad file was created and the records that were loaded were again NULL.
The input file has a list of emails: iatraveler2008@aol.com iaz65@aol.com 2blue2brown@comcast.net 2c3mwilson@embarqmail.com abigailolschan@comcast.net imisskoco@aol.com
I tried FIELDS TERMINATED BY X'10' and FIELDS TERMINATED BY X'13' too for new line and carriage return respectively. This time there were no bad file created, but the Table has Null values.
Log File contents:
Number to load: ALL Number to skip: 0 Errors allowed: 10000 Bind array: 64 rows, maximum of 256000 bytes Continuation: none specified Path used: Conventional Silent options: FEEDBACK, ERRORS and DISCARDS

Below are the step i followed.
1. In table testtablename, I have added new column COLUMNNAME29 with datatype VARCHAR2(8). 2. After adding the new column, i executed the update query to populate the data form COLUMNNAME1 to COLUMNNAME29. 3. The query is executed using COLUMNNAME24 in where clause, to drive query in index based.
SQL> desc testtablename Name Null? Type ----------------------------------------- -------- ---------------------------- COLUMNNAME1 VARCHAR2(8) COLUMNNAME2 CHAR(1) COLUMNNAME3 CHAR(1) COLUMNNAME4 VARCHAR2(8) COLUMNNAME5 VARCHAR2(11)
[Code]...
Table altered.
SQL> select index_name, column_position, column_name from dba_ind_columns where table_name = 'TESTTABLENAME' order by index_name,column_position;
1. The update query is hanging in database, it's not progressing (In single update, approximately 40000 records will get update) 2. No oracle error thrown in alert log or in session where the query being executed. 3. The event for the query is "db file sequential read". 4. When i update the newly added column COLUMNNAME29 with static value "1", the update completed successfully in few seconds. 5. Then i changed the static value to "1111" and executed the update statement, which result to query hanging in database. 6. I tried to update the existing column(COLUMNNAME1) in table with static value "1111", the update completed successfully.
Below are the queries completed successfully
Update Testtablename Set Columnname29 = '1' Where Columnname24 >= To_Date('01-12-2002 00:00:00', 'DD-MM-YYYY HH24:MI:SS' ) And Columnname24 < To_Date('01-01-2003 00:00:00', 'DD-MM-YYYY HH24:MI:SS')

I'm getting back more than I want. I need to get the latest row in the PS_ACAD_STDNG_ACTN that has the academic standing code for students.
I thought if I max the effdt, strm, and effseq I would get back only one row. Especially effdt since a academic status is hardly ever updated on the same date.
PS_NTSR_GF_STUFILE will have multiple emplid's for students taking classes. PS_ACAD_STDNG_ACTN should have the last standing status for each student..(PRO = Probation, DIS = Dismissed).
UPDATE PS_NTSR_GF_STUFILE a SET a.NTSR_GF_ENRL_STAT = nvl(( SELECT b.GBSA_SUB1 FROM PS_GBSA_DTL b, PS_ACAD_STDNG_ACTN c WHERE c.ACAD_STNDNG_STAT = b.GBSA_VALUE
In the table the names are having diffrent spaces for one name only one space between the words,for another name two spaces between words,for other names three spaces between the words.
I want to update with single space how can we that.
I am giving the data as follows.
CREATE TABLE student(sname VARCHAR2(30));
INSERT INTO student VALUES('PRAKASH BABU'); INSERT INTO student VALUES('RAJESH KUMAR'); INSERT INTO student VALUES('POORNA CHANDAR'); INSERT INTO student VALUES('ANIL RAJ'); INSERT INTO student VALUES('ABHI RAM KONA'); INSERT INTO student VALUES('SRI TEJA MEDI');
Like this the table contains millions of rows.
I want to update the names like this.
PRAKASH BABU RAJESH KUMAR POORNA CHANDAR ANIL RAJ ABHI RAM KONA SRI TEJA MEDI
Can I achieve the merge (update-only) and delete in a single SQL statement?
merge into table_4 using (select table_3.col1 col1,table_3.col2 col2, from table_1, table_2, table_3 where [code].....
delete from table_3 where <records identified in the 'using' clause of above merge>;
i.e.
delete from table_3 where (table_3.col1,table_3.col2) in ( select table_3.col1,table_3.col2, from table_1, table_2, table_3 where join conditions..... other conditions .... group by table_3.col1, col1,table_3.col2 having count(*) >1 );
What I want is roughly as following :
WITH mywith as ( select table_3.col1,table_3.col2, from table_1, table_2, table_3 where join conditions..... other conditions .... group by table_3.col1, col1,table_3.col2 having count(*) >1 ) update table_4 set col3='N' where table_4.col1=mywith.col1 and table_4.col2=mywith.col2 delete from table_3 where table_3.col1=mywith.col1 and table_3.col2=mywith.col2;
I would like to insert a value if that value is not existing in the table (example for a column which contains date only new dates should be inserted and if the date already exists in the column then it needs to get updated )
example of scenario...
date s1 s2 s3
in the above if the date is new..it should get inserted with the appropriate slot no.(s1,s2,s3) if the date already exists it needs to update the no.in slot no.
